Parameters

Parameter label	I/O type	Data type	Mandatory parameter?	Default value
inputVec1	input	vector/scalar	yes
inputVec2	input	vector/scalar	yes
operator	input	string ("+"/"-"/"*"/"/"/"log")	no	"+"
divisionByZeroResultsInZero	input	bool	True	“value”
outputVec	output	vector	N/A	N/A

Functionality

If both inputVec1 and inputVec2 are vectors, the module performs the operation given in operator between all corresponding pairs of elements in inputVec1 and inputVec2. If at least one of both input vectors is a scalar, the operation is applied between the scalar and all elements of the other input vector. If operator is set to log, the element-wise natural logarithm of all elements of inputVec1 is computed and returned as outputVec.

If divisionByZeroResultsInZero is True, all division-by-zeros will return 0 instead of Inf.

Here are some simple examples:

operator="+"
inputVec1 = [1,1,1]
inputVec2 = [1,2,3]
...
outputVec = [2,3,4]

operator="+"
inputVec1 = [1,1,1]
inputVec2 = [8]
...
outputVec = [9,9,9]

operator="*"
inputVec1 = [1.1]
inputVec2 = [3]
...
outputVec = [3.3]

operator="log"
inputVec1 = np.array([np.e, np.e**2])
...
outputVec = [1,2]
